Windows 7: how to install win7 witout losing vista on my laptop!

hi guys.
i have a Sony Vaio VGN-CS325J that comes with Windows Vista Home Premium x64,now i am going to install windows seven x64 on my laptop but i don't want to lose my vista as a matter of fact i want to have dual boot win vista & seven.
is it possible?
(my Vista is installed at Drive C and i have an empty Drive that is F with NTFS file system and 50GB space)
regards

Could you post a screen shot of Disk management?

I;m not quite sure about the upgrade path,. but I';ll find out.

i wouldnt recommend to do dual boot.. if you want to try windows 7 just install in virtual machine like MS virtual pc 2007 and try it, if you like then just back up your whole system into a image file using utillites like "macrium reflect", save the image somewhere for future use (if you need vista later) and do a clean install of windows 7, you feel so much better

or

if you really need windows 7 as dual boot, just insert the installation disk, boot through the disk, during installation select the hard drive you want to install windows 7.. that is it windows will handle boot loader, you dont have to configure anything for dual boot. if you decided to play around with boot loader then use the application called "Easy BCD".

all the applications i mentioned above are free.. Google it.
these are just my personal opinion, if like take it otherwise just ignore!

sure.

I made a mistake the Drive that i want to install it is J that now has 41.8GB free space
but my problem is not which drive shoud i install,my problem is that has anyone tested dual boot vista and seven?

thanks for your respnse.
before i have installed Windows 7 on my pc and i love it,so i decided to install it on my laptop.
actually i don't want to miss win vista because for my laptops some drives hasn't released yet.
u told just insert installation DVD and install ony my appropriate drive,and after that what will hapeen at boot loader?

Yes you can install it there and WIndows 7 will configure the dual boot perfectly. Boot from the Windows 7 DVD and choose Custom install for the Advanced drive tools to format the partition first. You will also want to plug in ethernet so you can stay connected to the internet during install as the installer is so driver complete it will update itself during install and deliver more in first Windows Updates.

MS funded the WHQL partnership with all manufacturers to build Windows 7 drivers so they have them first now, unlike before.

When you start up, check the Device manager for any missing drivers: use Driver tab on Device to Update driver, browsing to the Vista Windows/system32/drivers and /driverstore files to find those drivers.

When you are ready to get rid of Vista, you'll want to remove that EISA partition (google for special Diskpart commands) in the prime disk position since it is only able to perform recovery for Vista while Vista is still installed. The MBR will stay in Vista for now, but can be recovered into Windows 7 later using Startup Repair.

People are wanting to bail out of dual boots in hours and days now instead of weeks and months that it took us beta testers. We do many of them each day, and each is its own special puzzle, but doable with about a 90% success rate. Your best bet is a dual boot to acclimate to Windows 7 and transfer files, since you can't easily plug in another HD.

We're here when you are ready to say Hasta La Vista.

wooooooooooooooow niceeee yes i'll format it manually before starting installation.
u mean on boot loader i'll have two choice between them?

Yes, Windows 7 bootmanager will take over as such, and write it to the boot [partition. That is to say, when you install Windows 7 on J, you will have WIndows 7 as your default install and Vista will be the secondary one... so all should be fine.

however, most likely, when you log into windows 7 , J will become C and when you are on Vista , it will be also C. This can be somewhat annoying and also create some discrepancies in hardcoded paths (eg. created by yourself).

What you can do, which I often do , since C is reminaed as C... is to do in windows 7 cmd >

bcdedit [/enum all] > bcdwin7.txt (nevermind the /enum all option really)

save it on D lets say or whatever but easy to find even if drive letters change

then cmd : bcdedit > d:\bcdVista.txt

Log back into Vista..

in cmd type :

bcdedit /export D:\bcdbackup

also :
and then cmd (RUN AS ADMINISTRATOR!!) type > bootsect.exe /nt60 all /force

(YOu might need ot go to c:\windows\boot}

now do bcdedit again and compare with your bcdwin7 and bcdvista txt files to see if you nderstand whats happening...

in either case... you will see you will have to do somethign like:

current (now is vista) , osdevice and device must be changed to C: if they r not

to do this: bcdedit /set {current} device partition=C:
bcdedit /set {current} osdevice partition=C:

for the win 7 which you will recognise by studying your two files , having somethign like {XXXXXXXxxxxxXXXxxxx-XXXXXXXx--XXXX} (i dont remember right now , im doing this just off the top of my head) but anyway, when you have recognized which one it is

you do bcdedit /set {THE WIN 7 GUID yes that long number, copy n paste from text file)} device partition=J:
bcdedit /set {GUID} osdevice=J:

good luck.. if it fails dont panic... come back here n have another computer ready or recommended!!! a winpe disk on usb

thanks dear solar

Here is the Seven Forums tutorial: Dual Boot Installation with Windows 7 and Vista

It leaves out formatting so be sure after booting from the DVD and choosing Custom install, to click on the partition where you want to install, choose Advanced drive tools and format the drive you have highlighted.

Windows 7 configures the dual boot leaving the MBR in Vista but with boot files in Windows 7.

It configures a dual boot menu appearing at boot-up which will let you choose which OS you want to enter. The timeout on the menu is set for 30 seconds after which it will enter Windows 7.

You can change this timeout, the default OS, or even hide the menu in Start>right click Computer>Properties>Advanced Tools>Startup and recovery.
